Cuttlefish
The cuttlefish, actually a cephalopod relative of octopuses and squid, can shift shape and change its skin color to hide from danger by impersonating its surroundings—like a chunk of a coral, a clump of algae, or simply a patch of sand. The animal’s skin holds some ten million color cells and functions like a high-definition TV that fine-tunes color change so effectively the U.S. military has studied the animal in hopes of improving its own camouflage techniques.
